Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below.
As shown in fig. 1 to 9, the industrial robot end comprises an industrial robot end housing 1 and a spindle 2 of the industrial robot end.
A cylinder component which is arranged at the tail end of an industrial robot and can transmit gas comprises a gas passing outer sleeve 3, a gas passing inner sleeve 6 which is sleeved in the gas passing outer sleeve 3 and synchronously rotates with the tail end of the industrial robot, and a cylinder piston 8 which does telescopic motion in the gas passing inner sleeve 6. The cylinder component designed by the invention can synchronously rotate with the tail end of the industrial robot on one hand, and can transmit outside air through the cylinder component after the cylinder component is adopted on the other hand, so that the air pressure transmission is realized on the basis of ensuring the self-rotating function of the cylinder component, the winding problem of the traditional pipeline type industrial robot is effectively solved, and the normal operation of an execution part of the industrial robot is ensured.
The outside air is divided into two paths to enter the air passing outer sleeve 3, one path is used for controlling the cylinder piston 8 to do telescopic motion, the function of a cylinder is achieved, and then the force of the telescopic motion is output; the other path is output through the air passing outer sleeve 3, so that air passing operation is realized, the traditional air pipe connection mode is replaced, the air passing inner sleeve 6 can rotate freely, normal transmission of air pressure can be guaranteed, and mutual interference is avoided.
The air passing inner sleeve 6 is provided with a group of first air passages 14 for controlling the cylinder piston 8 to do telescopic motion and a group of second air passages 15 which penetrate through the air passing inner sleeve 6 and then output air. The first air passage 14 and the second air passage 15 are independent of each other.
The cylindrical outer surface of the air passing inner sleeve 6 is provided with a plurality of annular air passages 6a which are matched with the air passing outer sleeve 3, are not communicated with each other and are communicated with the corresponding first air passages 14 and the corresponding second air passages 15. The design of the annular air passage 6a ensures the continuous supply of air in the rotating process of the air passing inner sleeve 6, and the structural design is ingenious.
The air passing outer sleeve 3 is provided with a group of first air inlet and outlet holes 16 which are communicated with the corresponding annular air passage 6a and form an air passage channel for controlling the telescopic motion of the cylinder piston 8 with the first air passage 14, and a group of second air inlet and outlet holes 17 which are communicated with the corresponding annular air passage 6a and form an air passing channel with the second air passage 15. The external gas can be divided into two paths to be respectively injected into the first air inlet and outlet hole 16 and the second air inlet and outlet hole 17, and the two air paths are independent from each other and respectively execute independent operation.
The end that is close to industrial robot end shell 1 on the air passing outer cover 3 is equipped with the extension 3a that outwards swells, the middle part of extension 3a is equipped with the vertical groove 3b who separates into two parts with extension 3a, the one end that industrial robot end shell 1 was kept away from to extension 3a is equipped with the cross slot 3c that separates the lower part of extension 3a and air passing outer cover 3. The air passing outer sleeve 3 can be tightly fixed on the industrial robot end shell 1 by screwing bolts after penetrating through two parts of the extension part 3 a.
And one end of the air passing inner sleeve 6 close to the tail end of the industrial robot is connected with a transfer block 4 fixedly connected with the tail end of the industrial robot through an inner sleeve locking screw 5.
And a sealing plate 7 used for being matched with the air passing inner sleeve 6 to form a sealed piston cavity 13 is arranged at one end of the air passing inner sleeve 6 far away from the tail end of the industrial robot.
Be equipped with gas storage tank 13a on the terminal inner wall of being close to industrial robot on the sealed piston chamber 13 to behind the first business turn over gas pocket 16 department air inlet, through first air flue 14 transmission to gas storage tank 13a department, thereby make the cylinder piston 8 of complete contraction state receive the gas pressure effect to be released, possessed the function of cylinder.
The two air paths work independently, when the cylinder piston 8 needs to do telescopic motion, external air enters from the first air inlet/outlet hole 16, the cylinder piston 8 can be driven to extend out, and when the reset operation is needed, only the air paths need to be reversely ventilated; when needing to cross gas with the help of cylinder assembly, external gas is followed second business turn over gas hole 17 and is admitted air, exports behind second air flue 15, can take the gas of this department to satisfy the demand of actual production processing. When the air passing outer sleeve 3 needs to rotate together with the tail end of the industrial robot, the two air paths cannot be influenced.
